A High‐Throughput Composite Catalyst based on Nickel Carbon Cubes for the Hydrogenation of 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran

Abstract

A high‐throughput composite catalyst is prepared from porous carbon with an unconventional nanocube morphology decorated with nickel nanoparticles. Owing to the advantageous properties of the designed carbon support, the composite combines a high surface area and a hierarchical pore structure with high functionality. Furthermore, the regularly shaped nanocubes allow for a good packing of a fixed‐bed flow reactor, in which the internal transport pores cannot be blocked and stay open for efficient column performance. The composite is employed as a catalyst in the hydrogenation of 5‐hydroxymethylfurfural (HMF) to 2,5‐dimethylfuran (DMF), showing good catalytic performance and overcoming the conventional problem of column blocking.

Nickel on nitrogen-doped carbon pellets for continuous-flow hydrogenation of biomass-derived compounds in water

“…The reduction in the textural properties is attributed to the change in the mass density of the sample, as well as the coverage of the support surface and pores with Ni. 73 However, the specific surface area of the mesoporous material was found to be (∼100 m 2 g −1 ), cf. Table 1.…”

“…The freshly reduced 35Ni/NDC presents only typical reflections of Ni 0 at 2θ of 44°a nd 51°, which indicate the complete reduction of NiO after calcination and reduction processes. 73 The images obtained via high resolution scanning transmission election microscopy (HR-STEM) and scanning electron microscopy (SEM) are shown in Fig. 6 and Fig.…”

Biomass Sucrose‐Derived Cobalt@Nitrogen‐Doped Carbon for Catalytic Transfer Hydrogenation of Nitroarenes with Formic Acid

“…[24][25][26] Doping with nitrogen atoms can lead to as light distortion in the crystal lattice of the carbon materiala nd thereby cause defects. [4,[33][34][35][36][37][38] For example, Beller andc o-workersr eported the use of nanoscale iron(-III) oxide (Fe 2 O 3 )p articles surrounded by N-doped graphene layers for the selectivet ransfer hydrogenation of nitroarenes with hydrazine hydratea sh ydrogen source. [27][28][29] In the past decade, non-noblem etals incorporated into NC materials have not only become an alternative to noble-metal-based catalysts in electrocatalysis, [30][31][32] but also their excellent properties for catalytic hydrogenation have been reported.…”

Catalytic Hydrogenation/Hydrogenolysis of 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran

“…Transformation of HMF to DMF is scientifically an interesting reaction with a complex reaction network and this reaction has been intensively studied [14–62] . In the first step HMF is hydrogenated to BHMF followed by its hydrogenolysis to methylfurfuryl alcohol (MFA) and further hydrogenolyses to DMF.…”
